Which component of the x-ray unit contains the tube and transformers?

• A. Sensor
• B. Tubehead
• C. Tungsten Target
• D. X-radiation

Answer: (B)

The part that houses both the x-ray tube and the components that power it is the tubehead. It is the end of the unit that contains the x-ray tube itself and the high‑voltage equipment (like transformers) that provide the kilovoltage needed to produce x-rays. Inside the tubehead, the tube has the anode with the tungsten target, where x-rays are generated when electrons collide with it. The other options don’t describe a single component that encloses both the tube and its power transformers: the sensor is the image receptor, the tungsten target is a part of the tube itself, and x-radiation is the energy produced, not a physical housing.
